What does this mean and what exactly is your problem..... I was agreeing with you.
He was referring to axle gear ratio...which does play into it but with more gears in the transmission it's not as important anymore.

For instance, this little Bronco we have has 4.70 gears in the axles and 35" tires. With the 10 speed it's still laying down right about 20 mpg, despite having 4.70 gears.

The major difference between the 6 and 8 transmission is the intermediate gears, the first and final are similar.

Well, partially right. 1st gear is way lower on the 8 speed, and it does have a closer spread in the intermediate gears. The upper 3 gears are basically identical
1st gear on the 8 speed is 4.7 where as the 6 speed is only 3.23. So initial take off acceleration is way stronger on the 8 speed, plus add in the closer spacing of 2nd-5th gears. That is on paper and from my experience. When shopping for a truck in 2019, the first year for the 8 speed in the 2500's, I test drove several 2018 and older with the 6 speed and several 2019 with the 8 speed back to back. The 8 speeds definitely felt stronger but did wind up buying a super clean low mileage 2016 because it was $20k cheaper than a new 2019 at the time.
For highway cruising the top 3 gears are almost identical between the two trans, and those are the gears you will be in 99% of the time when cruising over 50 mph.
So yes, an 8 speed truck will feel much better on take off and stop and go driving with big tires. But cruising on the highway it will still feel a little sluggish with big tires.

"1st gear is way lower on the 8 speed,"

What are the 1st gears in each???????????????????

"But cruising on the highway it will feel a little sluggish with big tires."

So, will it with marshmallows for tires at mfg tire specs.

4.71:1 on the 8, 3.23:1 on the 6.

So if both have a 4.10 rear gear the final drive ratio on the 8 is around 19:1 in first gear vs 13:1 on the 6 speed.

Even if you go and install 4.88 rear gear in the 6 speed you don’t end up with the final drive ratio of the 8 speed in first.

Not sure what your point is other than just trying to argue with people.......
If you actually read all of my post I stated exactly what the 1st gear ratios are in both transmissions. Second gear in the 8 speed is very similar to what first gear is in the 6 speed.
Not sure what the marshmallow comment is supposed to mean. My point is that if you put 37's on the truck will feel the same on the highway regardless of which transmission it has.

Right! I was checking to see if you were one of the few here who actually know what they are talking about.

The gear ratios for the 2023 Ram 2500 with a 6-speed transmission are:
  • 1st: 3.23
  • 2nd: 1.84
  • 3rd: 1.41
  • 4th: 1.0
  • 5th: 0.82
  • 6th: 0.63
The gear ratios for the 2023 Ram 2500 4x4 Mega Cab 6'4" Box with an 8-speed transmission are:
  • First gear: 4.71
  • Second gear: 3.14 ***** 1st
  • Third gear: 2.11
  • Fourth gear: 1.67 ***** 2nd
  • Fifth gear: 1.28 ****
  • Sixth gear: 1.00 *****s
  • Seventh gear: 0.84 *****s
  • Eighth gear: 0.67 ******s

A lot of people put down the 6 speed BUT, in reality all the 8 speed does is gives a bit faster start (1st) and a better 3rd gear. The 8 feels better/smoother simply because it has more gears for the transmissions.

The 6 to 8 in the 8 are equal to the 4th to 6 in the 6.

Hi I think all of you are missing the point a 1500 vehicle is a light weight vehicle with a semi floating, or at best 3/4 floating rear axle. These are not designed for heavy hauling, or heavy rear axle loads. A 2500 or 3500 will have a fully floating rear axle, i.e a commercial axle. For putting heavy weights onto a vehicle, this is what you need. For the record a fully floating axle allows you to withdraw the halfshafts with the wheels on the floor. Overloading a light weight axle will eventually lead to premature wheel bearing failure. I say this from experience.
Regards Marcus

This gap was always my issue. With my 11K 5th wheel attached the truck just couldn't hold 2nd in some scenarios. Trying to go up a moderate hill at 30-40MPH just wasn't going to happen. Choices were leaving it in "D" and letting the truck just slam back and forth between 1 & 2, or just locking in 1 and taking it at 25-30. I chose to lock in and slow down, much to the disappointment of those behind me, I'm sure.

Lower rear end would help but that gap is going to be an issue at any reasonable number.

I wouldn't call a 2500 rough by an means, but you will certainly notice a difference. I have a 1500 sierra that is definitely a smoother ride around town, but when you put a small load on it you notice right away, while my 2500 ram you will legitimately not even notice until you have several thousand pounds behind you.
Someone else in my family has a 2500 power wagon, and it's noticeably stiffer than my 1500. It's not horrible by any means, but it isn't a 1/2 ton truck. This one is also a power wagon with the smoother suspension.

Yeah you can't really go based off a Power Wagon when it comes to comparing 1500 and 2500 suspensions. I had a Power Wagon, softest riding HD truck I've ever owned. Still stiffer than my wife's old F150 or 1500, but not as jarring as my current CTD 2500. That happens when, even when going to a MUCH heavier motor, I still gained something like 400 lbs of payload capability.

You might try a transmission fluid change and adding LUBEGARD Synthetic Automatic Transmission Fluid Protectant to avoid the 'slam' and using tow/haul mode if you have it.

Distance and duration are an important consideration.
Towing something for a 100 miles 3 or 4 times a year in the midwest is an entirely different thing than touring the mountain west for 6 weeks at a time.

I towed a 3,000 pound trailer about 25,000 miles in 2 years with our Gladiator. Despite it being less than half the tow rating and well inside cargo capacity of the Gladiator it was a miserable chore. Did it do it? Sure. Was it safely inside "ratings"? Yes. Would I recommend a Gladiator (JTR) to anyone to use as we did? Absolutely not.
Thanks for the honest answer. I towed with my Tacoma but it too was miserable so I moved to a full size.
